What Makes This Recipe Unique?
I value the importance of a healthy breakfast, and I love a breakfast that works hard for me. This baked oatmeal checks all the boxes: it’s healthy, affordable, make-ahead friendly, and honestly, just plain delicious.
- Pantry-Friendly - If your long-term storage is well stocked, you probably already have all the ingredients you need on hand. Nothing fancy, just real food ingredients for cooking from scratch.
- Budget-Wise - Are you learning how to save money on groceries? Oats stretch a dollar a long way, which makes this recipe perfect for feeding a crowd (or stocking up the fridge for the week).
- Family-Approved. The texture is like a soft breakfast cake—lightly sweet, cozy, and full of flavor. Even picky eaters come back for seconds.
- Flexible - Swap in whatever you’ve got: blueberries, apples, pumpkin, nuts, even chocolate chips. You really can’t mess it up.
- Make-Ahead Magic - Mix it up the night before, pop it in the oven in the morning, and breakfast is done before the coffee finishes brewing.
Key Ingredients
For a full list of ingredients and measurements, check out the recipe card below.
- Rolled Oats – Old-fashioned rolled oats hold their texture best. Quick oats get mushy, and steel-cut oats just take too long.
- Yogurt – You can use plain store-bought, but we use homemade Instant Pot yogurt, which is even creamier.
- Eggs – Farm-fresh if you have them! Just remember safe handling practices.
- Sweetener – Choose what you love: pure maple syrup, honey, or sugar. If you’re using syrup or honey, use about two-thirds the amount since they’re sweeter.
- Butter - We use this homemade butter recipe.
Favorite Mix in Combinations
Here’s where you can make it your own!
- Blueberry Peach - A summertime favorite.
- Cranberry Pecan - Perfect for the holidays.
- Apple Raisin Cinnamon - Classic and cozy.
- Chocolate Peanut Butter - For a fun twist, reduce butter and sugar to ¼ cup each, add 1 cup peanut butter, ½ cup cocoa, and 1 cup chocolate chips.
- Fruit Purees - Use 1½ cups of mashed banana, Instant Pot applesauce or homemade pumpkin puree and reduce water to ½ cup for a moist and flavorful delight!
Homesteading Hack: Frozen or dried fruit works just as well as fresh—don’t let the season stop you!
Recipe Instructions
Step 1: In a large bowl, whisk together yogurt, milk, water, eggs, sweetener, melted butter, vanilla, and cinnamon. (If you’re using banana or pumpkin puree, add it now.)
Step 2: In a separate bowl, stir the baking powder into the oats to distribute evenly.
Step 3: Combine the oats with the wet mixture and stir until fully incorporated. Pour into a lightly oiled 9×13-inch pan, and sprinkle your chosen mix-ins over the top and stir gently to distribute.
Step 4: Bake right away at 350°F for 1 hour, OR cover and refrigerate overnight. If you’re baking from cold: place the cold pan into a cold oven, then preheat to 350°F and bake for about 1 hour and 10 minutes total (including preheat time). You’ll know it’s done when the top is golden brown and the center is set.
Serving and Storage Instructions
Serve warm with a splash of milk, a dollop of yogurt or this delicious breakfast sausage recipe. Store leftovers in the fridge for up to 4 days. They reheat beautifully or can be eaten cold on the go. It’s just as delicious cold, so don’t stress about reheating leftovers—if you even have any!
Recipe Tips
- This recipe can easily be halved and baked in an 8×8 or 9×9 pan. Reduce baking time to 40 minutes.
- Allowing the oats to soak in yogurt for up to 24 hours before baking breaks down the grain’s phytates (anti-nutrients) and unlocks the oats’ nutrition, making them easier to digest and better for you.
- This recipe is great for make-ahead meal prep. Just mix the whole recipe up to a day in advance and then leave it in the refrigerator until baking time. Homesteading Hack: Remember to start cold glass pans in a cold oven so they don’t break!
